Research Of Web Service Matching Model And Service Matching Arithmetic Based On OWL Language And Description Logic

Web Services are loosely coupled software components delivered over Internet standard technologies. The main idea of Web Service is publishing, finding and binding service.In order to realize precise location of Web Service and get better Web Service, we must provide an efficient Web Service finding and Web Service matching mechanism. A Web Service matching model which can realize intelligent Web Service matching based on description logic and ontology is provided in this paper. The model includes five parts, that is, Web Service regestry, Web Service inference, Web Service matching , Web Service provider and Web Service requestor .A Web Service matching arithmetic is improved in this paper. The service matching arithmetic is three-level matching arithmetic, concept level, function level and nofunction level. Through level-depatching mechanism, correction and precision is improved. Lastly, Web Service matching procedure is analized corresponding concret example. In order to solve multi-service results problem, service depatching method from bottom level to upper level is provided.In order to improve information seaching correction and precision, Web Service matching system based on description logic and ontology is applied to CIQS, as a result, the lack of traditional information seaching based on keyword is avoided.
